Abstract

Soil was percolated with water and various nutrient solutions, and then the percolates were analyzed for bacteriophages which produced plaques on various Arthrobacter strains. The water percolates did not contain detectable phage. In contrast, phages for A. globiformis strains ATCC 8010 and 4336, and for several recent Arthrobacter species soil isolates, were easily detected in nutrient broth, soil extract, and cation-complete medium percolates. These percolates did not contain phage that produced plaques on A. oxydans and a recent Arthrobacter species soil isolate. Percolation with a selective nicotine-salts solution was required for demonstrating phage for these bacteria. None of the percolates contained phage for five additional named Arthrobacter species. In addition, phages were not detected for A. crystallopoietes in a 2-hydroxypyridine percolate of soil. Based on their lytic spectra, the phage isolates from this soil were relatively host specific.
